In experiment 1, 100 Indian River chicks, 1 day old, were assigned to 15 pens and fed until 49 days of age on diets in which 0, 10, 20, 30 or 40% CP contributed by soyabean oilmeal (SBM) was substituted by CP from shrimp meal (SM). Experiment 2, 52 chicks were assigned to 16 pens and offered diets in which 0, 60, 80, and 100% CP contributed by SBM was replaced by CP from SM, until 42 days of age. In experiment 1, body weight, feed intake, feed conversion efficiency, mortality, carcass weight and yield were not influenced by dietary treatments. In the second experiment, body weight was higher (P<0.01) at21, 28, 35 and 42 days of age in treatments in which SBM was completely replaced by SM (100%). No significant differences were observed for feed intake, feed conversion efficiency, mortality or carcass yield in any of the treatments. Carcass weight increased significantly by 12.1% when 100% SM was used. It is concluded that the shrimp meal used in this study could partially or totally replace soyabean oilmeal in broiler diets without negatively affecting performance or carcass quality.
